Answer:
5/23
Step-by-step explanation:
23 students, 18 females so 5 males
In this case, the probability of a male student being chosen at random from the class is 5/23.
Definition of classical probability:The probability of an event is the ratio of the number of cases favorable to it to the total number of cases possible when nothing leads us to expect any of these cases to occur more than any other, making them equally possible for us.
i.e. probability of an event = number of the possible outcome of an event/number of total outcomes in the sample space
What is an event?An event is a set of outcomes of an experiment to which a probability is assigned in probability theory.
What is a sample space?A sample space is a set of possible outcomes from a random experiment.
How to solve this problem?Here, the random experiment, in this case, is "a student chosen at random from the class". There are 23 students in the class. So, the number of total outcomes in the sample space is 23. Let us consider the event as “the randomly chosen student is a male”.
Since there are 18 female students in the class, so the number of male students is (23-18)=5.
i.e. the number of the possible outcome of this event is 5.
Therefore the classical definition of probability, we can conclude that
Required Probability = 5/23
Hence the probability that a student chosen randomly from the class is a male is 5/23.

Addison livers 1/5 of the newspapers in the neighborhood and I need a delivers 1/2 of them after Addison and I need to deliver the newspapers what fraction of newspaper newspaper is remain.
Answer:
3/10
Step-by-step explanation:
If Addison livers 1/5 of the newspapers in the neighborhood and I need a delivers 1/2 of them, the total fraction of paper used will be;
1/5 + 1/2
= (2+5)/10
= 7/10
The fraction of the paper left = 1 - 7/10
The fraction of the paper left = (10-7)/10
The fraction of the paper left = 3/10

Choose the polynomial that is written in standard form 7x^5+8x^8+27x
Don’t need the answer just couldn’t find the question lol so the answer is 3
Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3

Each square below represents one whole.
What percent is represented by the shaded area?
Answer:
160%
Step-by-step explanation:
Because the first square (the one to the left) is shaded to the brim, it represents 100%.
The second square (the one to the right) is shaded only until the 6th row, we can say that it is shaded 6/10 rows, or 60%.
Lastly, add the percentages of the two squares => 100% + 60% = 160%

If you flip two coins 64 times, what is the best prediction possible for the number of times
both coins will land on heads?
I need help quick this is a math unit test and it’s not 32 !
Answer:
The best prediction possible for the number of times both coins will land on heads is 16.
Step-by-step explanation:
For each time the two coins are flipped, there are only two possible outcomes. Either they both land on heads, or they not. Coin flips are independent, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
On a trial, probability of two heads.
Each trial has two coins, each with 0.5 probability of landing on heads. So the probability of two heads on a trial is:
[tex]p = (0.5)^2 = 0.25[/tex]
64 times
This means that [tex]n = 64[/tex]
What is the best prediction possible for the number of times both coins will land on heads?
The expected value. So
[tex]E(X) = np = 64*0.25 = 16[/tex]
The best prediction possible for the number of times both coins will land on heads is 16.
